VICI - Your Chromatographic Components Specialist Company Description
Founded in 1968 by Stanley Stearns in his own living room, VICI has since grown to become an international organisation with devices found in nearly every national lab, military facility, and university research department around the globe. For 50 years VICI has pioneered new instrumentation, helping scientists to measure and make sense of the world. We create highly customised solutions for some of the most difficult separations chemistry challenges today.
Facilities
With over 150 state-of-the-art CNC machines, our instruments and components are manufactured to exacting standards at our facilities in Houston, USA and Schenkon, Switzerland. VICI Metronics, located in Washington state, produces permeation devices and calibration gas standards for a range of trace detection industries. VICI Precision Sampling in Baton Rouge, Louisiana manufactures analytical syringes, micro valves, and custom formed tubing.
Major Products/Services
Valco produces a complete line of valves for analytical chemistry. We specialise in zero dead volume fittings and filters for the separation sciences and are the original creators of the pulse discharge dectector (PDD). Our miniPDD consumes less than one-fifth the amount of helium required by the PDDs used on complete GC systems. It has similar sensitivitiy to the original PDD with a slightly lower dynamic range.
Our VICI Metronics division produces PEEK, FEP, PFA, and ETFE tubing, ambient temperature gas purifiers, ValcoBond GC capillary columns, and Dynacal gas calibration standards. The VICI Precision Sampling division manufactures analytical quality syringes, sampling probes, and standard and custom formed stainless and special alloy tubing. VICI AG (Valco International) produces the Jour line of HPLC fittings and lab safety products.
Our newest products include the C82 line of UHPLC valves, fittings that permit direct connection of 360 um tubing, the Universal valve actuator, and the C52 platform integrated HPLC injectors and selectors.

New VICI Components for Fast GC
Mud logging supplies important data to the exploratory drilling industry. This data has historically been provided by an isothermal GC method, but the method is slow.
Fortunately, VICI - Valco Instruments’ newly designed multi-zone temperature controller can dramatically speed up this process. It can accurately control GC component temperature with different sensing methods - wire, RTD, TC. The heating element is bundled tightly along the column for uniform heating and also functions as the sensing element.
With this technology, a C1-C5 gas mixture analysis can be completed within 12 seconds. The cool down time is less than 18 seconds, for a total run time of less than 30 seconds - with good sensitivity, repeatability, and linearity.
The fast column temperature method can result in faster analysis, smaller column size, higher sensitivity, and less power consumption.
